=== Overview ===
This site provides download and installations instructions for the - [2018 Introduction to Modeling Lithospheric Dynamics Tutorial].

The tutorial utilizes the mantle convection and lithospheric deformation code [ASPECT], which has been precompiled on a virtual machine along with other software. The virtual machine will be run with !VirtualBox.

Please note that all of the required software and files should be downloaded and installed *BEFORE* the tutorial.

If you have any questions about the tutorial or problems arise with the software installation please contact help@geodynamics.org.

=== Tutorial Prerequisties ===
==== Virtualbox ====
You can download !VirtualBox [here] and please use [https://www.virtualbox.org/manual/ch02.html  directions] to install !VirtualBox.

If your host machine is any linux system, both {{{virtualbox}}} and {{{virtualbox-dkms}}} packages must be installed. Also check to make sure you have exFAT filesystem drivers. Windows and Mac systems should have it by default. On Ubuntu, the packages required are {{{exfat-utils}}} and {{{exfat-fuse}}}.

We recommended that your computer have at least 20 to 30GB of free disk space and preferably 4GB of RAM.

==== Tutorial Image ====
We will use virtual box to boot up a ubuntu 14.04 linux OS image titled ASPECT-tutorial-2.0.ova.

This image contains the following software packages pre-installed:

  * ASPECT
  * dealII
  * Paraview
Please download [ASPECT-tutorial-2.0.ova] onto laptop you are going to use for the tutorial. The image is ~2.6 Gb, so please allow plenty of time for the download and use a high-speed internet connection if possible.

==== Importing the CGU18 tutorial image ====
  # Run !VirtualBox.
  # Select from the menu “Import appliance”: 
     [[Image(cgu18_select_import_appliance.png)]]
  # Select the downloaded ASPECT-tutorial-2.0.ova: 
     [[Image(cgu18_select_vm_image.png)]]
  # Select Continue and Import: 
     [[Image(cgu18_import_vm.png)]]     
  # Click on start (the green arrow) to launch the image: 
     [[Image(cgu18_start_green_arrow.png)]]
==== Using the Image ====
Now simply start the ASPECT-tutorial virtual machine.
